I have 5 girls who have been producing eggs since September so they are about 10 months old. They've been awesome producers laying an egg daily to every other day even during the short CO days. We only turn on the heat lamp when it gets down to the low single digits or below to keep the water from freezing. About a week ago we went 2 days without collecting eggs and came out to 11! Since then not one of them has laid an egg. I thought possibly broodiness from how many eggs we left in there but none of them are nesting. In fact they've started pooping in the nesting boxes but are still coming out during the day. I think they are too young for molting. I'm concerned, but they aren't acting sick. Help, we are so new to this.
